I recently bought a (presumably) low-quality pair of headphones. Both sides work, but will only play audio from the left channel. Weirdly, I cannot get the right headphone to work with any other pair of properly functioning headphones that use the jack. I was told this was from water damage by a phone shop employee when asking about repairs, but I can't see this being the problem if the pair I have now is working on both sides -- it is just the right audio channel itself that won't work. However, Bluetooth headphones do work properly. Does anyone have the same problem, or know what would cause this? I've been dealing with this problem almost since I got the phone a few years ago and it's getting frustrating.
